Presenter

Dr. Mark A. Richards

Dr. Mark A. Richards is a Principal Research Engineer and Adjunct Professor of Electrical and Computer Engineering at the Georgia Institute of Technology. He has been engaged for over 30 years in radar signal processing research, primarily at the Georgia Tech Research Institute (GTRI) where he last served as Chief of the Radar Systems Division. His work focused on topics such as millimeter wave target detection and classification, electronic warfare for imaging radars, airborne windshear detection, and embedded extreme-scale ISR applications. Dr. Richards is a Fellow of the IEEE cited “for contributions to radar signal processing education”. He is the editor-in-chief and author of multiple chapters of the text Principles of Modern Radar: Basic Principles and the sole author of the text Fundamentals of Radar Signal Processing, second edition. He is the developer and lead instructor of several professional education “short courses” in radar signal processing and synthetic aperture radar.

Fundamental Tradeoffs in Synthetic Aperture Radar (SAR)

Synthetic aperture radar (SAR) is a remote sensing technology capable of providing detailed two- and three-dimensional images of terrain and man-made structures and objects around the clock and under virtually all weather conditions. SARs are hosted on platforms ranging from small unmanned air vehicles, to commercial and military manned aircraft, to earth orbiting satellites, and have a host of scientific, commercial, and defense applications.

An ideal SAR would provide fine resolution, high sensitivity imagery of large areas in a short time. In practice, the achievable resolution, sensitivity, and area rates are determined by basic system parameters such as power, bandwidth, standoff range, antenna design, processing capability, and more. In this webinar, Dr. Mark Richards summarizes representative performance goals for a few broad classes of SAR applications and how they depend on basic radar parameters. In this context, he then shows how these goals sometimes interact and conflict, requiring the SAR engineer to tradeoff key system characteristics such as antenna size and PRF, or resolution and area coverage. Because data processing, requirements can also become a critical bottleneck, the increasingly important issue of onboard processing power efficiency vs. data link capabilities, especially in small platforms such as UAVs, will be described.
